Jamides for ID

[bluefin]

Came across this small Lycaeninae in CCA, this fella is quite small, about size of a Malayan. I think this is a Jamides and I can't seems to find a match in the checklist.
The small round dot on the forewing looks interesting.

Any assistance in ID would be great.

Wingshape & markings are consistent with a female Common Caerulean J. celeno.
Perhaps a restricted food source had stunt its growth.

Thanks Seow, for assisting in the ID.

A change in the expressed phenotype (e.g. wing pattern, size, colour..) of a genotype (e.g. butterfly, grasshopper, moth.. etc), when is influenced by the environmental factors (e.g. poor quality or lack of host plant, fluctuation of temperature, photoperiodism - hours of day light and dark period, adult food quality and source..etc), all these factors not only influence the morphology and also their behaviour.

Numerous research reports documented the changes of insects (including butterflies) morphology and behaviour. One of the example is the dry and wet season forms of Precis octavia from Africa. Our local butterflies like Mycalesis mineus, Melanitis leda..etc also show morphological phenotypic plasticity. A recent photo posted by Khew: Lethe minerva is a dry season form.
